About
Can't sleep because your mind won't stop?
Opening Line gives you one quiet sentence: the first line of a calm scene. Read it, close your eyes, and let your mind write the rest. Before long the day's worries have nowhere to go, and you drift off.
It's based on a simple idea that sleep researchers call cognitive shuffling: picturing calm, unrelated scenes tells your brain it's safe to let go. No breathing exercises, no long stories to follow.
SLEEP MODE
Tap the moon when you're in bed. The screen fades to black, a soft voice reads the scene aloud, and gentle background sound plays until the timer ends. Nothing to look at, nothing to tap.
185 SCENES IN 6 WORLDS
• Cozy: a mountain cabin in the rain, a warm bakery, snow outside the window
• Wander: night trains, slow rivers, a ferry to a small island
• Encounters: small, kind moments with strangers and old friends
• Whimsy: a bed that floats above the clouds, a whale in the bathtub
• Time Travel: poets, tea houses and old harbors
• Little Mysteries: a door you never noticed, a key found on the beach
Nothing scary, nothing that drags you back into your own worries.
SHUFFLE MODE
A new, unrelated scene is read to you every minute or two until you're asleep. This is cognitive shuffling on autopilot.
ALSO
• Brown noise, pink noise and ocean swell, made on the device
• Favorites, and write your own openings
• Morning check-in and a simple sleep log; Apple Health optional
• Bedtime reminder that carries tonight's first line
• Warm amber and ember text colors for the dark
• No account, no ads, no tracking
Cozy and Wander scenes, sleep mode with voice and brown noise, and the sleep log are free. Opening Line Pro is a one-time purchase that adds the other 4 worlds, shuffle mode, all sounds and timers, your own openings and full history.
Opening Line is a relaxation aid, not a medical device. If sleep problems persist, please talk to a doctor.
